U.S. regulators are supposedly investigating whether JP Morgan Chase (NYSE:JPM) failed to properly monitor transactions, enabling criminals to launder money.

Royal Dutch Shell (NYSERDS.A) (NYSE:RDS.B) will delay its hunt for oil off the Alaskan Arctic until 2013 after a dome that would be used to hold oil in the instance of a spill, had been damaged in testing.

With the short drilling season in the Arctic’s Chuckhi Sea, Shell continues waiting for final permits to enable them to proceed.

The U.S. Treasury Department is supposedly unwilling to sell the government’s General Motors (NYSE:GM) stake because a sale would result in large investment losses. Earlier this year, GM reportedly floated a plan with Treasury officials to repurchase 200 million of the approximate 500 million shares held by the U.S. government of the company, with the Treasury selling the remaining shares via a public offering; the government is disinterested in GM’s offer at the current price. With GM’s Friday close share price at $24.14, the U.S. would lose almost $15 billion on the GM bailout if the entire stake was sold.

Over the weekend, anti-Japanese protests exploded in China during a territorial dispute that could affect trade ties between the large Asian economies.

The two countries have a long dispute over a group of uninhabited islands in the East China Sea; this contains the potential for large natural gas reserves.
